  • Article Friis Glaser
    International Journal of Community Currency Research 2018 VOLUME 22 (SUMMER) EXTENDING BLOCKCHAIN TECHNOLOGY TO HOST CUSTOMIZA- BLE AND INTEROPERABLE COMMUNITY CURRENCIES Gustav R.B. Friis* and Florian Glaser** * Brainbot Technologies AG, Mainz ** Karlsruhe Institute of Technology (KIT), Karlsruhe ABSTRACT The goal of this paper is to propose an open platform for secure and interoperable virtual community currencies. We follow the established information systems design-science approach to develop a prototype that aims to combine best practices for building mutual-credit community currencies with the unique features of blockchain technology. The result is a specification of an open Internet platform that enables users to join and to host customized community currencies. The hosted currencies can be classified as credit-based future type of money with decentralized issuance. Furthermore, we describe how the transparency, security and interoperability properties of blockchain technology offer a solution to the inherent problems of existing, centrally operated community currency software. The characteristics of the prototype and its ability to fulfil the design-objectives are examined by a relative evaluation against existing payment and currency systems like Bitcoin, LETS and M-Pesa.

  • Reputation Driven Dynamic Access Control Framework for Iot Atop Poa Ethereum Blockchain
    Reputation Driven Dynamic Access Control Framework for IoT atop PoA Ethereum Blockchain Auqib Hamid Lonea,∗, Roohie Naaza aDepartment of Computer Science and Engineering., NIT Srinagar, Jammu and Kashmir,India,190006 Abstract Security and Scalability are two major challenges that IoT is currently fac- ing. Access control to critical IoT infrastructure is considered as top security challenge that IoT faces. Data generated by IoT devices may be driving many hard real time systems, thus it is of utmost importance to guarantee integrity and authenticity of the data and resources at the first place itself. Due to heterogeneous and constrained nature of IoT devices, traditional IoT security frameworks are not able to deliver scalable, efficient and manage- able mechanisms to meet the requirements of IoT devices. On the other hand Blockchain technology has shown great potential to bridge the missing gap towards building a truly decentralized, trustworthy, secure and scalable environment for IoT. Allowing access to IoT resources and data managed through Blockchain will provide an additional security layer backed by the strongest cryptographic algorithms available. In this work we present a rep- utation driven dynamic access control framework for IoT applications based on Proof of Authority Blockchain, we name it as Rep-ACM. In Rep-ACM framework we build two major services, one for Reputation building (for bet- ter IoT device behaviour regulations) and other for Misbehaviour detection (for detecting any Misbehaviour on object resource usage). Both of these services work in coordination with other services of proposed framework to determine who can access what and under what conditions access should be granted.

  • Exploring the Interconnectedness of Cryptocurrencies Using Correlation Networks
    Exploring the Interconnectedness of Cryptocurrencies using Correlation Networks Andrew Burnie UCL Computer Science Doctoral Student at The Alan Turing Institute [email protected] Conference Paper presented at The Cryptocurrency Research Conference 2018, 24 May 2018, Anglia Ruskin University Lord Ashcroft International Business School Centre for Financial Research, Cambridge, UK. Abstract Correlation networks were used to detect characteristics which, although fixed over time, have an important influence on the evolution of prices over time. Potentially important features were identified using the websites and whitepapers of cryptocurrencies with the largest userbases. These were assessed using two datasets to enhance robustness: one with fourteen cryptocurrencies beginning from 9 November 2017, and a subset with nine cryptocurrencies starting 9 September 2016, both ending 6 March 2018. Separately analysing the subset of cryptocurrencies raised the number of data points from 115 to 537, and improved robustness to changes in relationships over time. Excluding USD Tether, the results showed a positive association between different cryptocurrencies that was statistically significant. Robust, strong positive associations were observed for six cryptocurrencies where one was a fork of the other; Bitcoin / Bitcoin Cash was an exception. There was evidence for the existence of a group of cryptocurrencies particularly associated with Cardano, and a separate group correlated with Ethereum. The data was not consistent with a token’s functionality or creation mechanism being the dominant determinants of the evolution of prices over time but did suggest that factors other than speculation contributed to the price. Keywords: Correlation Networks; Interconnectedness; Contagion; Speculation 1 1. Introduction The year 2017 saw the start of a rapid diversification in cryptocurrencies.

  • Ethereum Vs Ethereum Classic Which to Buy Update [06-07-2021] It Has Fully Compatibility with Solidity and Thus Ethereum Eco-System
    1 Ethereum vs Ethereum Classic Which to Buy Update [06-07-2021] It has fully compatibility with Solidity and thus Ethereum eco-system. It offers scalable and instantaneous transactions. It means that L2 projects are going to have a field day ahead with the increasing integrations and maturity of infrastructure around them. Therefore, it s the first entry in our top 5 Ethereum layer 2 projects list. Essentially it s a mixed PoW, PoS algorithm which it s purpose is to arrive one day to a PoS full implementation. Or will a completely new evolution of Ethereum be necessary to reach that level of transaction capacity. 380 transactions per block. Another important improvement is the next. More miners. Last week, the Ontario Securities Commission approved the launch of three ETFs that would offer investors direct exposure to Ether, the second-largest cryptocurrency by market capitalization after Bitcoin. 75 after May 31, the company said, plus applicable sales taxes. Management fees are not the only thing investors will need to pay. What to Know. Still, hopes of a technical adjustment called EIP ethereum improvement proposal 1559, which is expected to go live in July and is seen reducing the supply of ethereum, has provided a lift for the digital currency. Technically, ethereum is the blockchain network in which decentralized applications are embedded, while ether is the token or currency that enables or drives the use of these applications. It hit a record high of 3,610. Ethereum is well off its highs, though, so let s see if now is the time to make an investment.

  • Blockchain Implementation Method for Interoperability Between Cbdcs
    future internet Article Blockchain Implementation Method for Interoperability between CBDCs Hyunjun Jung and Dongwon Jeong * Department of Software Convergence Engineering, Kunsan National University, Gunsan 54150, Korea; [email protected] * Correspondence: [email protected]; Tel.: +82-(063)-469-8912 Abstract: Central Bank Digital Currency (CBDC) is a digital currency issued by a central bank. Motivated by the financial crisis and prospect of a cashless society, countries are researching CBDC. Recently, global consideration has been given to paying basic income to avoid consumer sentiment shrinkage and recession due to epidemics. CBDC is coming into the spotlight as the way to manage the public finance policy of nations comprehensively. CBDC is studied by many countries. The bank of the Bahamas released Sand Dollar. Each country’s central bank should consider the situation in which CBDCs are exchanged. The transaction of the CDDB is open data. Transaction registers CBDC exchange information of the central bank in the blockchain. Open data on currency exchange between countries will provide information on the flow of money between countries. This paper proposes a blockchain system and management method based on the ISO/IEC 11179 metadata registry for exchange between CBDCs that records transactions between registered CBDCs. Each country’s CBDC will have a different implementation and time of publication. We implement the blockchain system and experiment with the operation method, measuring the block generation time of blockchains using the proposed method.
